I'm not shure if all browsers have one. But Internet Exploler does. The Home Button is the button that says Home. It's across the top of the browser. With the back, forward, stop, refresh, search, ect, buttons. If you know how, you can change what your home-page is. Your home-page is the page your browser goes to when you first open it up, or when you push the Home button. I didn't think I would have to explane that, even though I misspelled button. I was just woundering who had their's on the Fungi Forums. I wouldn't recomend changing it if you share it with your parents, siblings, ect. They may like thier homepage. I change mine quite a bit.
